The baby (fetus) in the womb is located in a fluid called
amniotic fluid. This fluid not only protects the baby in the womb against
external trauma, but also allows the baby to grow and develop.
The diagnosis of oligohydramnios is made by low amniotic
fluid measurement (ASI) on ultrasound. Oligohydramnios means that ASI (four
quadrant measurement total) is less than 50 mm or the deepest vertical pocket
measurement is less than 20 mm.
The causes
of oligohydramnios are:
- Kidney absence or dysplasia
- Urethral obstruction, ureteropelvic junction stenosis
- Other conditions that cause obstruction in the urinary
tract
- Some anomalies of the fetus
- Early rupture of the membranes (EMR)
- Placental dysfunctions
- Intrauterine growth retardation
- The mother's waters have come
- Chromosomal anomalies
- TTTS (twin to twin transfusion syndrome) and TRAP
- Placental insufficiency
- Preclampsia, hypertension
- Pregestational diabetes (can also make polyhydramnios)
- The mother used drugs such as NSAI or ACE Inhibitor during
pregnancy
- Hypothyroidism in the fetus
Complications
that may develop due to oligohydramnios:
Oligohydramnios facilitates the development of meconium
aspiration, cord compression, fetal distress. Arm and leg deformities
(deformity) and pulmonary hypoplasia (restriction of lung development) may
occur in the fetus. The risk of developing amniotic band syndrome increases.
Treatment:
When oligohydramnios is detected, if the pregnancy is
terminated or if there is a day-out, the baby is delivered. If it is seen
earlier and if an anomaly is not detected in the baby, it may be possible to
give fluid to the amniotic cavity by amnioinfusion method, but this is not a
tried method. These fetuses are mostly waited until strict maturation time.
